The overall operation flow of the train broadcast control system according to the present invention having the system configuration as described above will be described again through the train broadcast control method (see FIG. 3) according to another embodiment of the present invention.

First, prior to operating the train, it is necessary to set the broadcast schedule for each train as shown in Table 1 (S 10).

The broadcast schedule is a satellite broadcast program received through the satellite broadcast receiver 16 and moving picture data stored in the removable HDD 27 with reference to the train's running route, the station to be stopped and the stop time before the train departs. Set the broadcast schedule using.

In particular, the satellite broadcast program transmits a specific program at a predetermined time from a broadcaster that transmits satellite broadcasts, and thus, refers to obtaining a broadcast program and setting a schedule.

In addition, the broadcasting schedule stores moving image data or still image data including advertisement contents (product and company advertisements, local information, municipal administration, national affairs) together with other moving image files on the removable HDD 27, and uses the advertisement. You can adjust the schedule to do this.

When the setting for the broadcast schedule is completed as described above, the broadcast schedule file is stored in the HDD 25 or the removable HDD 27, and the image data and the advertisement data for broadcasting are stored in the removable HDD 27. To the broadcasting systems 5a to 5c.

When the preparation for the broadcast is completed as described above, the train operation is started, and before the departure of the starting station, a guide broadcast according to the train operation is broadcast to the passengers.

After this process, when the train operation is started (S 11), broadcasting according to the broadcast schedule is started (S 12).

Assuming that the broadcasting schedule is set as shown in Table 2 below for the train number 100 in Table 1 above, 07:00, the departure time for the Saemaul train with the train number 100 departing from Seoul Station, which departs at 07:00 About 10 minutes before the departure of the train announcements for the train operation to the passengers.

Stop station · Seoul · · · Daejeon · Dae-gu · Busan Broadcast Schedule · · First video broadcast First advertisement · Satellite broadcasting 2nd advertisement Satellite broadcasting Second video broadcasting · Broadcast contents Departure announcement · · · Daejeon Stop Guide · Daegu Stop Guide · Busan Destination Guide · Scheduled time 06:50 07:00 08:10 To 08:20 08:30 09:50 10:00 12:50 13:00

Then, when the train leaves Seoul Station, the first video file is extracted from the removable HDD 27 according to the broadcast schedule, reproduced through the MPEG processing unit 32, and displayed through the switching box 40 and the overlay box 50. Broadcasts up to about 08:10 through 60 and the earphone jack and earphone 62.

When the first video file ends, the first advertisement is broadcasted according to a broadcast schedule. The first advertisement starts about 20 minutes before arriving at Daejeon station and ends about 10 minutes, and guides the station to stop at Daejeon station again. Perform a broadcast.

When the stop station guide event is finished as described above (S 17), broadcasting according to the broadcast schedule is resumed (S 18).

In addition, a case in which a caption message is transmitted through the display 60 is as follows.

Passengers traveling by train remain blocked from new information while on the train. Therefore, in the event that a socially important event occurs, the administrator who operates the remote control apparatus 1 organizes the contents into text data, and the first wireless modem 3b, the first communication terminal 3, and the first. It transmits through the antenna 3a.

When the control unit 20 receives a text message (eg, an SMS message) received through the second antennas 6a to 6c and the second communication terminal 12, the controller 20 processes it as a caption image (S 151). It outputs through the second video processor 30, which is overlaid with the video signal currently being broadcast through the overlay box 50 and displayed on the display 60 (S152).

When the closed captioning is terminated (S17), broadcasting according to the broadcasting schedule is performed again (S18).

Finally, the satellite broadcast event needs to provide passengers with information if a satellite broadcast program containing socially important contents is being broadcast from the remote control manager's point of view.

In this case, like the caption broadcasting, an interrupt is generated in the control process of the control unit 20 by using the first communication terminal 3 and the second communication terminal 12 to stop the content currently being broadcast (S). 161, the satellite broadcast receiver 16 is controlled to receive the currently broadcast satellite broadcast program and output the same to the switching box 40, and simultaneously control the switching box 40 to be output to the satellite broadcast receiver 16. The video and audio signals are output to the display and the earphone, respectively (S 162), so that passengers can watch satellite broadcasts.

When the satellite broadcast transmission by the interruption is finished (S17), the broadcast according to the broadcast schedule is transmitted in the same manner as in the event (S18).

While performing the broadcast as described above, when the operation of the train is terminated (S 19), the announcement is finally performed according to the termination of the operation of the train, and the broadcast is terminated (S 20).

The present invention made as described above provides a variety of information through a variety of media to the passengers traveling by train to immediately know the socially important content, to make a pleasant trip for a long time, to provide a variety of information Provides the effect of satisfying needs.
